Kids Day is an on-air event to encourage young people (licensed or not) to have fun with Amateur Radio and takes place Sunday January 8.

The Kids Day operating event is not a contest. It’s a way to tell young people worldwide about the magic and mystery of two way hobby radio communications.

To do this, Amateur radio stations are being asked to devote this short time window to promote the terrestrial hobby and ham radio satellite operations to youngsters. This, by providing a place to make contacts with other Kids Day stations around the world.

HOW TO READ PROPAGATION NUMBERS

The A index [ LOW is GOOD ]

1 to 6 is BEST

7 to 9 is OK

11 or more is BAD

Represents the overall geomagnetic condition of the ionosphere ("Ap" if averaged from the Kp-Index) (an average of the eight 3-hour K-Indices) ('A' referring to amplitude) over a given 24 hour period, ranging (linearly) typically from 1-100 but theoretically up to 400.

The measure of total radio emissions from the sun at 10.7cm (2800 MHz), on a scale of 60 (no sunspots) to 300, generally corresponding to the sunspot level, but being too low in energy to cause ionization, not related to the ionization level of the Ionosphere.

The overall geomagnetic condition of the ionosphere ("Kp" if averaged over the planet) over the past 3 hours, measured by 13 magnetometers between 46 & 63 degrees of latitude, and ranging quasi-logarithmically from 0-9. Designed to detect solar particle radiation by its magnetic effect. A higher K-index generally means worse HF conditions.
